Which Operating Systems Support aria2?

This article provides a comprehensive overview of the operating system compatibility for aria2, a lightweight, multi-protocol, and multi-source command-line download utility. It details the officially supported platforms—including Linux, Windows, and macOS—as well as its availability on Android, iOS, and various Router OS environments.

Officially Supported Operating Systems

aria2 is designed to be highly portable and resource-efficient, allowing it to run natively across all major desktop and server operating systems. Because it is written in C++, it can be compiled for almost any platform that has a modern C++ compiler.

• Linux: aria2 is native to the Linux ecosystem. It is available in the official repositories of virtually every major distribution, including Ubuntu, Debian, Fedora, Arch Linux, and CentOS/RHEL. It can be easily installed via standard package managers like apt, dnf, or pacman.
• Microsoft Windows: Full Windows support is available. Pre-compiled binaries are provided for both 32-bit and 64-bit Windows architectures. It runs seamlessly via the Windows Command Prompt, PowerShell, or within the Windows Subsystem for Linux (WSL).
• macOS: aria2 runs natively on macOS. Mac users can easily install it using popular package managers such as Homebrew (brew install aria2) or MacPorts.

Mobile and Embedded Operating Systems

Beyond traditional desktop environments, the lightweight nature of aria2 makes it an excellent choice for mobile devices, network storage, and embedded hardware.

• Android: While there is no official GUI application from the original developers, aria2 can be installed on Android via terminal emulators like Termux. Additionally, several third-party download managers on the Google Play Store use aria2 as their underlying download engine.
• iOS: aria2 can run on iOS, though it typically requires a jailbroken device to be installed via command-line tools, or deployment through specialized side-loaded applications.
• Router and NAS OS (Embedded Linux): Due to its low memory footprint, aria2 is heavily utilized in embedded environments. It is officially supported and widely used on custom router firmwares like OpenWrt, DD-WRT, and Tomato, as well as Network Attached Storage (NAS) operating systems like TrueNAS, Synology DSM, and QNAP QTS.

BSD and Other Unix-like Systems

For users operating on specialized server environments, aria2 maintains strong compatibility across the broader Unix-like ecosystem. It is actively maintained in the ports collection of FreeBSD, OpenBSD, and NetBSD, ensuring robust performance for advanced networking setups.
